Opublikowano<\/a><\/noindex> wydanie mened\u017cera okien xfwm4 4.14.3<\/a><\/noindex>, u\u017cywanego w \u015brodowisku u\u017cytkownika Xfce do zapewnienia wy\u015bwietlania okien na ekranie, dekorowania okien oraz organizowania ich przesuwania, zamykania i zmiany rozmiaru. <\/p>\n

W nowym wydaniu dodano<\/a><\/noindex> wsparcie dla rozszerzenia X11 XRes<\/a><\/noindex> (X-Resource), kt\u00f3re jest wykorzystywane<\/a><\/noindex> do zapytania z serwera X informacji o PID aplikacji uruchomionej przy u\u017cyciu mechanizm\u00f3w izolacji sandbox.

W nowym wydaniu r\u00f3wnie\u017c naprawiono<\/a><\/noindex> wykryto luk\u0119, kt\u00f3ra mo\u017ce prowadzi\u0107 do dost\u0119pu do ju\u017c zwolnionego obszaru pami\u0119ci (use-after-free) i zapisu danych poza przydzielonym buforem podczas przetwarzania ci\u0105g\u00f3w z ustawieniami.
